GoAir — cancellation of flight by the airline before 48 hours of travel date

Address:

1st floor C1, Wadia International Centre, Pandurang Budhkar marg Worli, Mumbai City, Maharashtra

I had a booking of two pax from banglore to indore on 26-jan-20. Pnr d3s19f, flight g8-403. The price of which was rs 6963 for two tickets.
I got a regret for the flight cancellation message from the flight on 23-jan-20.
On option for which airline denied any other flight availability and offered only the refund of my booking amount. But in this case i had to go for an alternate booking which costed me rs 10912. The extra cost i paid should be bearable by the airline, as it is there mistake.

Kindly register my complaint and provide justice to me
